On iOS 14.5 and later, we request your permission through Apple's App Tracking Transparency (ATT) framework before accessing your device's Identifier for Advertisers (IDFA). The IDFA is used to deliver personalized advertisements and measure the effectiveness of advertising campaigns.

You may choose to allow or deny tracking when prompted. If you deny tracking, we will not access your IDFA, and you may still see ads, but they will be less personalized. You can change your tracking preferences at any time in your device settings.

4.5 Your Advertising Choices

You have choices regarding the collection and use of your information by advertising services:

• iOS: Go to Settings > Privacy & Security > Tracking to manage which apps are allowed to track your activity across other companies' apps and websites.
• Android: Go to Settings > Google > Ads to opt out of personalized ads or reset your advertising ID.

Please note that opting out of personalized advertising does not mean you will not see ads; it means the ads you see may be less relevant to you.

4.6 Geographic Targeting

Advertisements displayed within the App may be targeted based on your general geographic region, as determined by your IP address. We do not use GPS or precise location data for ad targeting purposes. The geographic information used is approximate and typically only identifies your city or region.

4.7 Rewarded Video Advertising

The App offers optional rewarded video advertisements. By choosing to watch a rewarded video ad, you may receive temporary access to premium features (such as 2 hours of premium access). Watching rewarded ads is entirely voluntary and is not required to use the core features of the App.

5. Information We Collect

The App does not require you to create an account to use its features. We collect minimal personal information:

• Email Address: Only if you voluntarily contact our support team via email. We do not require or collect email addresses during normal app usage.
• Subscription Information: If you purchase a subscription, Apple (or Google) processes the payment. We receive subscription status information (active, expired, trial) from Apple/Google but do not receive or store your payment card details, billing address, or other financial information.
